IMPROVEMENT IN MOLDS FOR CASTING AND CHILLING SLEIGH-SHOES.

Specification forming part of Letters Patent No. 127,738, dated June 1l, 1872.

Speciiication describing a new and Improved `Moldfor Casting and Chilling Sleigh-Shoes,

invented by VOLNEY A. BUTMAN, of Ironton, in the county of Sauk and State of Wisconsin.

Figure 1 represents a top view; Fig. 2, a longitudinal vertical section; Fig.3, avertical transverse section of my improved mold for casting and chilling sleigh-shoes. Fig. 4 is a longitudinal, and Fig. 5 a vertical transverse, section ofthe same, showing the same in place.

Similar letters of reference indicate corresponding parts.

Thisinvention pertains to improvement in chill-molds for sleigh-shoes; and consists in a certain construction of parts, as hereinafter described and subsequently claimed.

A in the drawing represents the lower part or nowel of the iiask. B is the upper part or cope of the same. The nowel is made of castiron, with a cast-iron bed or bottom, a, whose surface is so arched as to give the requisite curved form to the shoes cast upon it. The

sides b b of the nowel are cast separate and project upward, and are also made of metal and firmly fastened to the bed a by means of bolts. The ends d d of the nowel are made detachable, being held by means of hooks to the projecting side pieces. This is for the purpose These patterns have at their lower edges projecting dowel-pins e e that't into corresponding apertures in the bed a, as shown in Figs. 2 and 3. The dowels serve the double purpose of keeping the patterns in place and of core prints.

When the sand has been placed in the nowel, and the patterns have been withdrawn, and connecting-chambers ff been formed in one end, as in Fig. 4, the cope B is applied on top of the nowel, said cope'bein g a wooden frame with transverse ribs g g and end handles h h, as shown. The process of casting is then carried out, the metal being chilled as it comes in contact with the bed a, and the shoes thereby being prepared for service.

The nowel-frame A is supported on wheels z' z', to be conveniently conveyed from place to place.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. The nowel-frame A, provided with the removable end pieces d d and the separate sides b b bolted to the bed a and mounted on the wheels c' z', substantially as herein shown and described.

2. The patterns() C having the dowel-pins and core prints e e, and combined with the metallic bed a of the nowel, as set forth.
